Hello ladies! My mother is 40+ years old and has issues managing her hair. She has very dense hair (high density on the top!) and has basically been gray/white since sometime in her 30's. She colors her hair about every 3 weeks (the white grows in pretty quickly). Her hair is very hard to manage. She's considered doing a keratin treatment, but she wants her curls, not straight hair.

Any advice for my beautiful mother?!
